This picture taken on October 17, 2015, released by Ou Zhihang, shows artist Ou Zhihang posing naked outside a house where four children drank pesticide after being abandoned by their migrant worker parents in Bijie, in China's southwest Guizhou Province.
The booksellers were later found to have been detained by Chinese authorities. Ou has taken more than 700 photos capturing his nude exercises on streets in China and sometimes abroad, including at sites of government abuses, protests and disaster - a body of work unmatched in the contemporary art world. / AFP PHOTO / HO / OU ZHIHANGOU ZHIHANG/AFP/Getty Images
